List Titles with KOSEKI Hazime

Kei and Yuri are incompetent members of the 3WA organization. Yuri is constantly late for work and often doesn't even bother showing up. Kei has disciplinary problems. Both have been suspended from 3WA many times. Forced to team together against their will, they are assigned the legendary code name of "Lovely Angels". But Yuri is mainly only interested in dates and Kei is only interested in not being bested at gunplay. Can this duo stop bickering long enough to actually get the job done and stop Waldess? And what happened to the original Lovely Angel team?
